The first mounting plate 11 is fixedly mounted on the upper end of the nozzle 6 by bolts. The second detection and calibration plate 10 is evenly distributed on the side end of the first mounting plate 11. The main detection and calibration unit 1 is fixedly mounted in the middle of the upper end of the support and limiting frame 2.
